Why Do Brake Calipers Stick?

Braking issues occur as the brake calipers start sticking to each other. The question is, why do brake calipers stick to each other? Below are the primary reasons that make the brake calipers stick to each other have been listed as follows:

Worn Out or Faulty Brake Hose

Faulty Brake Hose

Brake caliper sticking occurs due to a damaged brake hose. A worn-out hose often leads to leaks, preventing the brake fluids from returning to the master cylinder.

Worn or Faulty Brake Caliper Piston Boot

Sometimes the issues arise due to faulty brake caliper piston boot that needs the driver’s attention. Caliper piston has a rubber boot attached to it that keeps it lubricated and prevents debris entry inside it. A torn boot allows the debris entry into the caliper or rust formation within it. It also imposes a restriction on the sliding motion of the caliper.

Debris and Stuck Brake Pad Shims

Debris gets within the brake pad crevices, and sliding becomes a difficult task for the pads. Initially, the brake pad shims start sticking, followed by the sticking of brake pad calipers.

Brake Calipers Slide

Once you depress the brake pads, you’ll see that these start moving towards the grooves of the caliper. Rust and debris damage the brake pads to a great extent & pads start sliding out of them even if you’ve kept your foot aside.

Worn or Faulty Brake Caliper Bolts

The bolts present on the caliper need to be lubricated so that sliding and moving don’t become a difficult task for them. These bolts are enclosed with a protective rubber coating that prevents the lubricant leak. In case the rubber coating over the bolts breaks, these bolts dry up and lead to the accumulation of dust and debris.

You will notice that the car starts slowing down the moment you place your feet on the car. It is generally accompanied by a weird, irritating & high-pitched screeching sound. This often happens when the pad braking material starts wearing out.

Unexpected Heat Starts Dissipiating from the Affected Wheels
